1. A programmable audio message system comprising:

  • a clock to generate intervaled timing pulses;

    a plurality of audio message units, each of said units having;

    control circuit means conductively connected to receive said intervaled timing pulses and to generate a start control signal upon receipt thereof,tape player means conductively connected to receive said start control signal, said tape player having means to generate an audio signal and an audio output,an audio detect circuit conductively connected(1) to the audio output of said tape player to detect the presence of an audio signal and(2) to supply a run and stop signal to said tape player through said control circuit to cause said tape player to run as long as an audio signal is present at said audio output,tape means for positioning on said tape player, said tape being preprogrammed with a plurality of brief audio messages;

    speaker means associated with each of said audio message units conductively connected to the audio output of its respective tape player to receive audio signals therefrom and generate corresponding audible signals;

    wherein the intervaled timing pulses of said clock cause the control circuit of each message unit to start its respective tape player means in accordance with a time program to play the next brief audio message on said tape and the audio detect circuit of each respective message unit detects (1) the playing of the brief message at the audio output of its respective tape player to cause said tape player to run and (2) the absence of audio signals at the audio output to cause said tape player to stop; and

    wherein said tapes are preprogrammed by a tape programmer comprised of;

    tape recorder means havng an input with a microphone connected thereto to receive an audible input;

    digital time display means;

    control means conductively connected to said tape recorder means and to said digital time display means, said control means having;

    a counter control circuit conductively connected to said time display means to supply signals thereto to cause said time display means to display a preselected time,an audio monitor circuit conductively connected to detect the presence and absence of audio input to said tape recorder means and to send a pulsing signal to said counter control to advance the displayed time a preselected increment of time after detection of the presence of an audio input of selected duration followed by the absence of said audio input, said audio monitor circuit having means to inhibit recording for a selected period after the detection of said absence of said audio input.
